exists and is an alternate of .

Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!
Thanks for the feedback!

Why does a needle float on water but not on hexane?

Technically, a needle is heavier than water, so it doesn't really float in the usual sense of the word. It is suspended by surface tension between the water molecules on the s

Why is hexane not soluble in water?

Improved Answer When it comes to miscability, just remember this simple rule "Like dissolves like". In other words, the closer (chemically) two things are to each other, the

Does hexane dissolve in water?

Why do water and hexane do not mix?

Water is a polar molecule (is a dipole, has a positive end and a negative end), hexane is a non-polar molecule. Like dissolves like. Water will dissolve other polar molecules,

Why is ethanol soluble in water and hexane?

Ethanol is soluble in water because the -OH group of ethanol (CH3CH2OH) can form hydrogen bonds with water. Hydrogen bonding occurs when a very electronegative molecule like O
